Description

Technical Field

[0001] The invention relates to the technical field of intelligent lifeboats, in particular to an unmanned intelligent lifeboat with a salvaging robot. Background Art

[0002] In water rescue scenarios, traditional lifeboats mostly rely on manual driving and operation. Rescuers need to risk their lives to approach the waters where the incident occurred. When faced with severe sea conditions (such as strong winds, huge waves, and undercurrents), not only is their own safety threatened, but the rescue efficiency will also be greatly reduced. In addition, the navigation speed and path accuracy of manually controlled lifeboats are limited, making it difficult to quickly reach the target location in distress under complex water conditions.

[0003] With the continuous innovation and maturity of sensor technology, satellite positioning systems (such as GPS, Beidou and other high-precision positioning), and autonomous navigation algorithms (such as algorithms based on SLAM-simultaneous positioning and mapping, which enable lifeboats to perceive the surrounding environment in real time, draw maps and accurately position themselves), technical support is provided for the navigation control of unmanned intelligent lifeboats.

[0004] In conjunction with the above content, it should be explained that: Chinese patent with announcement number CN117302435A discloses an intelligent rescue boat in water areas and a method of use. It collects information about the surrounding environment of the water area and remotely controls the rescue boat to approach a designated location; however, during actual use, it only controls the direction of the remote movement of the rescue boat. When the rescue boat arrives at the rescue area, the personnel have been in the water for a long time to save themselves, and are prone to weakness or other abnormal conditions, which may lead to unexpected dangers to the people who fall into the water.

[0005] A Chinese patent with announcement number CN215851801U discloses a rescue frame for drowning persons on a boat, in which one side of the net is connected to the lifeboat, and the other side can be controlled and pulled by a lifeguard to pull up the drowning person in a lying position to prevent the drowning person from suffering secondary injuries during the salvage process; however, affected by factors such as the water environment and the rescue environment, the stability of the lifeboat itself is difficult to ensure when rescuing the drowning person, and safety hazards are still likely to occur.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figure 1 - Fig. 9 As shown, this embodiment is an unmanned intelligent lifeboat with a salvage robot, comprising a lifeboat body 1, a salvage storage box 2 is arranged at the bottom of the lifeboat body 1, and a long-distance stretching frame 3 connected to the outer walls of both sides of the lifeboat body 1 is arranged above the salvage storage box 2;

[0034] An air supply power box 4 is embedded in the center of the top of the lifeboat body 1, and a propeller 5 embedded in the tail of the lifeboat body 1 is arranged on the end face of the air supply power box 4. A salvage extension mechanism 6 is arranged inside the salvage storage box 2. The salvage extension mechanism 6 includes a lifting cylinder 601 and a telescopic mechanical arm 602, and a rotating bracket 604 and an external lifting airbag 605 are arranged on the end face of the telescopic mechanical arm 602;

[0035] A wireless communication module connected to the rescue center is provided at one end of the lifeboat body 1, as well as components such as a GPS sensor, a Beidou satellite navigation system sensor, a radar sensor, a sonar sensor, a camera and a gyroscope connected to the wireless communication module, which are used for the lifeboat body 1 to communicate with the rescue center and implement remote driving and rescue, but are not limited to this. They are all used for control integrated with existing technical means in this field, and are specifically replaced according to actual needs and the configuration of the lifeboat body 1.

[0036] Assembly frames 101 connected to the salvage storage boxes 2 are symmetrically arranged on both sides of the bottom of the lifeboat body 1. A servo motor and a screw frame are arranged inside the propeller 5. The servo motor is installed between multiple groups of salvage storage boxes 2, and the propeller is installed at the bottom of the tail of the lifeboat body 1 and submerged in water. When the lifeboat body 1 is remotely controlled by the rescue center and approaches the person who falls into the water, the rescue center personnel communicate with the person who falls into the water through the loudspeaker arranged on the lifeboat body 1 to inquire about the status and actively carry out rescue.

[0037] The lifeboat body 1 is adjusted by the propeller 5 to get closer to the person who falls into the water, and the salvage storage box 2 is adjusted toward the person who falls into the water. The box cover 201 is opened by the electric component, which includes an electric push rod, etc., which is assembled according to actual needs. The electric push rod is hinged with the inner wall of the salvage storage box 2 and the inner wall of the box cover 201 through relevant accessories. The booster air pump 401 continuously injects air pressure into the salvage storage box 2 through the aeration valve rack 204, so as to push the box cover 201 to open;

[0038] At the same time, according to actual configuration needs, a valve can be set at the bottom of the box cover 201 to temporarily connect the internal and external pressures of the salvage storage box 2, to assist the box cover 201 to open, and after subsequent resetting, to pressurize and inject air into the salvage storage box 2, so that the water entering the inside is squeezed out under the action of air pressure.

[0039] A box cover 201 is hingedly connected to the outer wall of the salvage storage box 2 on one side away from the lifeboat body 1, and multiple sets of rotating motors 202 are staggeredly arranged at both ends of the inside of the salvage storage box 2, and the rotating motors 202 are transmission-connected to the telescopic mechanical arm 602. A connecting frame 203 is arranged on the box body of the salvage storage box 2 on one side away from the box cover 201, and multiple sets of aeration valve frames 204 are arranged on the inner wall of the salvage storage box 2 close to the connecting frame 203, and the connecting frame 203 is bolted to the assembly frame 101;

[0040] The rotating motor 202 is connected to the telescopic mechanical arm 602 through relevant accessories. The relevant accessories include couplings, gears, screws and kits and other commonly used connecting parts in this field, but are not limited to them. The actual replacement is performed according to the component connection, and a matching connection method is given. The telescopic mechanical arm 602 is in a state close to the bottom wall of the salvage storage box 2. With the draft depth of the lifeboat body 1 due to its own weight, the telescopic mechanical arm 602 is located at a certain depth underwater, which is determined according to the size of the lifeboat body 1 and the size of the salvage storage box 2. Specifically, after the telescopic mechanical arm 602 is unfolded, it is convenient to extend to the lower body area of ​​the person who falls into the water.

[0041] The lifting cylinder 601 is sleeved on one end of the telescopic mechanical arm 602, and the lifting cylinder 601 is sleeved inside the salvage storage box 2. A plurality of groups of cushioning and crawling airbags 603 are arranged on the outer wall of the main arm of the telescopic mechanical arm 602. A plurality of groups of extending protrusions are arranged on the surface of the cushioning and crawling airbags 603. The extending protrusions expand and unfold as the cushioning and crawling airbags 603 are inflated, making it convenient for the rescued persons to hold and climb onto the lifeboat body 1.

[0042] Multiple groups of telescopic mechanical arms 602 are unfolded one by one, and the upper and lower cylinder bodies of the rotary cylinder 606 are started synchronously, driving multiple groups of rotating brackets 604 folded on both sides of the telescopic mechanical arms 602 to unfold one by one, forming four groups of fan-shaped structures on both sides of the lifeboat body 1, accompanied by the booster air pump 401 to inflate the crawling airbag 603 and the external lifting airbag 605 through the regulating valve and the air pipe;

[0043] The air supply pipe part is embedded in the telescopic mechanical arm 602 and the rotating bracket 604, and the cushioning crawling airbag 603 and the external lifting airbag 605 are simultaneously expanded by being injected with gas, and multiple groups of elastic threads are arranged inside the cushioning crawling airbag 603 and the external lifting airbag 605, so as to facilitate the contraction of the bag wall of the cushioning crawling airbag 603 and the external lifting airbag 605 by pulling, and the cushioning crawling airbag 603 and the external lifting airbag 605 expand upward after inflating, forming a structure that is wide at the top and narrow at the bottom.

[0044] A rotary cylinder 606 is provided at one end of the telescopic mechanical arm 602 away from the lifting cylinder 601. The rotary cylinder 606 is provided with two sets of upper and lower cylinder bodies and are arranged in reverse directions. A kit for connecting the rotary cylinder 606 is provided at one end of the frame of the rotating bracket 604. The external lifting airbag 605 is sleeved on the outside of the multiple sets of rotating brackets 604. The rotating bracket 604 is designed with a long and short structure according to the spacing requirements between the multiple sets of telescopic mechanical arms 602, and is specifically adjusted according to the actual size of the lifeboat body 1, and is not limited to what is shown in the accompanying drawings.

[0045] A temporary supporting structure is then formed at the bottom of the person who falls into the water, which helps to quickly relieve the emotions of the person who falls into the water under stimulation. Based on a certain buoyancy support and the power to actively climb onto the lifeboat body 1, multiple groups of air bags inflate at the same time, thereby increasing the contact area of ​​the lifeboat body 1 with the water surface, and effectively avoiding the problem of the lifeboat body 1 tipping over due to unilateral climbing by the person. In addition, according to the depth of the crawling air bag 603 and the external lifting air bag 605 immersed in the water, the height of them is adjusted by the lifting cylinder 601, which can not only assist the person who falls into the water to lift up to the water surface and climb onto the lifeboat body 1, but also adjust the buoyancy and draft of the lifeboat body 1 itself.

[0046] After the person who fell into the water is successfully rescued and climbs onto the lifeboat body 1, the booster air pump 401 begins to extract the internal air of the multiple sets of cushioning and crawling airbags 603 and the external lifting airbags 605, and the rotary cylinder 606 drives the multiple sets of rotating brackets 604 to reset, and the elastic wire pulls the multiple sets of cushioning and crawling airbags 603 and the external lifting airbags 605 to shrink, and the rotating motor 202 and the lifting cylinder 601 drive the telescopic mechanical arm 602 to rotate, and then reset it to the salvage storage box 2.

[0047] Embodiment 2: This embodiment is an unmanned intelligent lifeboat with a salvage robot, including a spray box 7 connected to a long-distance stretching frame 3 arranged inside the lifeboat body 1 on both sides, a plurality of groups of pressurized air cavities 701 are arranged inside the spray box 7, and a winding roller 704 is arranged between the plurality of groups of pressurized air cavities 701, and a traction line 705 connected to the long-distance stretching frame 3 is wound on the surface of the winding roller 704.

[0048] When a person falls into the water and there is a certain distance between him and the lifeboat body 1 due to the influence of the water environment and the water flow, the rescue center warns the person through the loudspeaker, and when the long-distance stretching frame 3 is directed toward the person, the booster air pump 401 increases the air pressure inside the booster air chamber 701 through the regulating valve and the air pipe;

[0049] Multiple groups of pressure relief valves are opened at the same time, and the gas enters the slide tube 702 along the pressure relief valves. The gas pushes the slide rod 703 along the slide tube 702, and the slide rod 703 moves quickly along the slide tube 702 and hits the long-distance stretching frame 3 along the slot, causing the long-distance stretching frame 3 to be thrown to the vicinity of the person who falls into the water under the impact. The person who falls into the water approaches the lifeboat body 1 through the long-distance stretching frame 3, and rescue is carried out with the opening of the cushioned crawling airbag 603 and the external lifting airbag 605.

[0050] A filter cover plate is arranged on the top of the air supply power box 4 and is clamped with the top of the lifeboat body 1. A booster air pump 401 is embedded inside the air supply power box 4. A regulating valve and an air supply pipe are arranged on the output end of the booster air pump 401. The air supply pipes are respectively connected to multiple groups of cylinders, a cushion crawling air bag 603, an external lifting air bag 605 and a booster air chamber 701. The air supply pipes are connected to relevant components through flanges.

[0051] A slide cylinder 702 facing the long-distance casting stretching frame 3 is arranged on the outer wall of one side of the pressurized air chamber 701, and a slide rod 703 is slidably sleeved inside the slide cylinder 702. A pressure relief valve connected to the slide cylinder 702 is arranged on the inner wall of the pressurized air chamber 701, and discs in contact with the inner wall of the slide cylinder 702 are arranged at both ends of the slide rod 703. A slot penetrating the lifeboat body 1 is arranged on the side of the slide cylinder 702 facing the long-distance casting stretching frame 3.

[0052] The end surface of the winding roller 704 is provided with a winding motor 706 connected to the inner wall of the spray box 7, and the side of the winding roller 704 facing the long-distance stretching frame 3 is provided with a through hole penetrating the lifeboat body 1, and multiple sets of guide wheels are provided on the inner wall of the through hole, and a storage groove opened on the outer wall of the lifeboat body 1 is provided on the outer wall of the through hole;

[0053] When the slide bar 703 moves rapidly along the inside of the slide tube 702, the winding motor 706 rotates actively and is connected to the winding roller 704 through relevant accessories, prompting the winding roller 704 to quickly unwind the traction line 705, and the traction line 705 moves along with the long-distance casting stretching frame 3. Then, according to the usage, the winding motor 706 starts to rotate in the opposite direction, driving the winding roller 704 to rotate and wind up the traction line 705.

[0054] In combination with Example 1 and Example 2, it can be known that the present invention realizes the flexible opening and resetting of the box cover 201 by salvaging the storage box 2 and its electric components, thereby improving the convenience and flexibility of rescue, and the telescopic mechanical arm 602, rotating bracket 604 and other components constitute a temporary support structure to provide buoyancy support for people who fall into the water and increase the stability of the lifeboat body 1. The lifting cylinder 601 adjusts the height of the airbag, which not only assists the people who fall into the water to get on board, but also adjusts its own buoyancy and draft to adapt to complex environments.

[0055] When the distance between the drowned person and the lifeboat body is large, the long-distance stretching frame 3 can be thrown to the vicinity, combined with the opening of the airbag, to improve the rescue measures, and the winding motor 706 and the winding roller 704 support the rapid unwinding and winding of the traction line 705.

[0056] The preferred embodiments of the present invention disclosed above are only used to help explain the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the invention to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification.
